Gang,

I figured it out!

* In the GRIDs MouseDown() Put this code.
*---------------------------------------------------------------
This.AddProperty("LastnXCoord", nXCoord)
This.AddProperty("LastnYCoord", nYCoord)

* In the GRIDs DoubleClick() Put this code.
*---------------------------------------------------------------
nComponent = -1
nRelativeRow = -1
nRelativeColumn = -1
This.GridHitTest( This.LastnXCoord, This.LastnYCoord, @nComponent, ;
@nRelativeRow, @nRelativeColumn )
IF nComponent = 3
* Put your doubleclick code in here...
ENDIF

Thanks for all the help!
